On the viability of FPGA-based integrated coprocessors

چکیده
This paper examines the viability of using integrated programmable logic as a coprocessor to support a host CPU core. This adaptive coprocessor is compared to a VLIW machine in term of both die area occupied and performance. The parametric bounds necessary to justify the adoption of an FPGA-based coprocessor are established. An abstract Field Programmable Gate Array model is used to investigate the area and delay characteristics of arithmetic circuits implemented on FPGA architectures to determine the potential speedup of FPGA-based coprocessors.

Control software for reconfigurable coprocessors
On-line data processing at the ATLAS general purpose particle detector, which is currently under construction at Geneva, generates demands on computing power that are difficult to satisfy with commodity CPU-based computers. One of the most demanding applications is the recognition of particle tracks that originate from Bquark decays. However, this and many others applications can benefit from p...

متن کاملPerformance of Remote FPGA-Based Coprocessors for Image-Processing Applications
This paper describes a performance evaluation of ImageProcessing applications on FPGA-based coprocessors that are part of general-purpose computers. Our experiments show that the maximum speed-up depends on the amount of data processed by the coprocessor. Taking images with 256 x 256 pixels, a moderate FPGA capacity of 10E+5 CLBs provides two orders of magnitude of performance improvement over ...
